Subject: [PATCH] ndctl: Fix the NDCTL_TIMEOUT environment variable parsing

Patch-mainline: v75
Git-commit: 61229759bfd184554a502654a0af83b40851cbbf

The strtoul(x, y, size) returns empty string on y when the x is only
a number with no other suffix strings. The code is checking if !null
instead of comparing with an empty string.
